Product introduction of Mercedes Benz GL350, ML350, S350 GTB2060VKLR Turbo 802774-0005：

  After the engine runs at high speed for a long time, it cannot be turned off immediately. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling. After the running engine suddenly stops, the oil pressure drops to zero rapidly, the high temperature of the turbo part of the supercharger is transmitted to the middle, the heat in the bearing support shell cannot be quickly taken away, and at the same time, the supercharger rotor is still rotating at a high speed under the action of inertia. Therefore, if the engine is suddenly stopped in the hot state, it will cause the oil retained in the turbocharger to overheat and damage the bearings and shafts. In particular, it is necessary to prevent the engine from suddenly turning off after a few kicks of the accelerator.

  As we all know, the engine generates power by burning fuel in the cylinder to do work. Since the amount of fuel input is limited by the amount of air drawn into the cylinder, the power generated by the engine will also be limited. state, and then increasing the output power can only increase the amount of fuel by compressing more air into the cylinder, thereby improving the combustion performance. Therefore, under the current technical conditions, the turbocharger is the only mechanical device that can increase the output power of the engine without changing the working efficiency

Precautions when using Mercedes Benz GL350, ML350, S350 GTB2060VKLR Turbo 802774-0005：

  Since the turbocharger often works at high speed and high temperature, the temperature at the turbine end of the turbocharger exhaust gas is about 600°C, and the turbocharger rotor rotates at a high speed of 832-1040r/min. Therefore, in order to ensure the normal operation of the turbocharger, use The following points should be noted:

1. You can't leave the car. After the engine is started, especially in winter, it should be allowed to idle for a period of time to allow the lubricating oil to fully lubricate the bearings before the supercharger rotor runs at high speed. Therefore, do not slam the accelerator after starting to prevent damage to the supercharger oil seal.

2.can not be turned off immediately. After the engine runs at high speed for a long time, it cannot be turned off immediately. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling. After the running engine suddenly stops, the oil pressure drops to zero rapidly, the high temperature of the turbo part of the supercharger is transmitted to the middle, the heat in the bearing support shell cannot be quickly taken away, and at the same time, the supercharger rotor is still rotating at a high speed under the action of inertia. Therefore, if the engine is suddenly stopped in the hot state, it will cause the oil retained in the turbocharger to overheat and damage the bearings and shafts. Therefore, after the engine is under heavy load and running for a long time, it should run at idle speed for 3-5 minutes before turning off the flame, and let the speed of the turbocharger rotor drop before turning off the flame.

Our factory produces：

All of the products are machinined by automatic CNC machines,for example turbine housing,compressor housing,bearing housing,etc.we also manufacture a few remaining parts, such as bolts, nuts, o-rings and ring for suppliers with specific requests.

In the process starting with 3D drawing, all CNC processes, 3D measurements, high speed balancing, quality control, assembly and packaging are done at our own production line.
